IVILLIAM VOSS, OF CHICAGO, ILLINOIS, ASSIGNOR TO THE FOX SOLID PRESSED STEEL COMPANY, OF SAME PLACE.

TRUCK.

SPECIFICATION forming part of Letters Patent No. 431,089, dated July 1 1890.

Application filed January 25, 1890. Serial No. 338,166. (No model.)

To all whom, it may concern.-

Be it known that I, IVILLIAM VOSS, of the city of Chicago, count-y of Cook, and State of Illinois, have invented anew and useful Im-. provement in Trucks, of which the following is a full, true, and exact description, reference being had to the accompanying drawings.

This invention relates to an improvement in car-trucks in which springs are interposed between the axle and the truck with the advantage of relieving the truck from the strain and jar which usually affect it.

My invention will be readily understood from the accompanying drawings,in which Figure 1 represents a plan; Fig. 2, a lateral elevation; Fig. 3, an end elevation; Fig. 4, a transverse section through the end of the bol ster; Fig. 5, a transverse section through the side frame and spring S, and Fig. 6 an inside elevation of one of the spring-pockets.

The truck-frame may be, except as to the parts herein specifically described, of any usual and proper construction; but I prefer to make the same of the side pieces C, of pressed flanged steel, and end pieces B, fitting thereto, and making, generally, a rectangular frame, as shown in Fig. l.

The bolster, as shown, consists of two flanged steel channel-beams A A, provided with center plate F, riveted thereto, and with side bearing-plates G G, likewise riveted or suitably fastened thereto. The ends of the beams A are bolted to the steel box K, as

shown in Fig. 4, the box' K and beams A A being bolted to the side frame C and additionally resting upon the plate H, bolted through the lower flange of the side frame C. A similar plate may be bolted over the tops of the beams A A, as shown in Fig. 1. The truck-frame does not-rest in this construction directly upon the axle-journals, but is carried on equalizing-levers O O. Theends of the levers O 0 rest upon the ends of the axles L L through interposed springs N N, while the side frames C C are hung upon equalizing-levers O 0 through links T T, 1he lower ends of which rest upon springs S S. The springs N N have their upper ends supported in the spring-caps P P and their lower ends carried upon the axle-journal through suitable brasses, the ends of the axles being guided in the pedestals in the usual way. The springs N N pass through cylindrical openings formed by the cylindrical depressions R R, and the internal semicylindrical covers R R, making cylindrical openings, through which the springs pass. These depressions R R are preferably pressed in the side frames in the process of manufacture. In these side frames are likewise pressed the cup-shaped depressions D D,which,when combined with theinner members of the cups, shown in Fig. 5, form a complete cup. The upper ends of the springs S S are supported in the spring-caps P P and the lower ends are carried in the caps, to which are attached the links T T, carried upward and attached to the equalizinglevers O O, as at V. In this wayit is obvious that the jar of the axleis transmitted through springs N Nand springs S S before reaching the side frames, truck, and bolster.

What I claim as my invention, and desire to'secure by Letters Patent, is

l. The combination, in a car-truck, of an equalizing-bar connect-ed to the axles of the truck, and springs between the bar and the truck-frame, the springs being supported in depressions in the frame, substantially as described.

2. The combination, in a car-truck, of two axles, two springs connected with said axles, and an equalizing-lever attachedto the frame of the truck by a spring-connection, substantially as described.

The combination, in a car-truck frame, of the springs S S, bearing upon the truckframe and interposed between said frame and the equalizing-lever O, the equalizing-lever O, and the springs N N, connected with the axle, substantially as described.

4. A truck side frame having pockets for the reception of the springs, consisting of lat-- eral recesses pressed in the side frame, and semi-cylindrical covers secured to the frame, substantially as described.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
